The ECV10-44 is a standard model EC10-40 in a convenient in-line plumbed body with an integral control cartridge cavity VC10-2. Addition of needle valves, rotary valves, electro-proportional valves, etc. allow for infi nitely variable pressure-compensated priority flow output.
The ECV10-44 maintains a constant flow rate from port R regardless of load pressure
changes in the circuit downstream of port R.
The cartridge maintains a constant differential pressure from port P to port R
(see USASI Symbol), thereby regulating the hydraulic flow rate between the two
ports. The ECV10-44 is a priority type regulator, delivering pump flow fi rst to R, then
bypassing excess to B. All ports may be fully pressurized. Flow output is a function
of the flow required to maintain a pressure drop as detemined by the compensating
spring value. The control cavity is cartridge port ➁ in, cartridge port ➀ out, so all cartridge restrictions on ➀ to ➁ use apply.
• Hardened parts for long life.
• Quiet, modulated response.
• Panel-mount capability.• Lock-down bracket holes.
